it is said conrad leffler lived in cocalico township lancaster pa and had a son john and through the census a son william. it is also proved that when conrad died in 1777 he had removed to oley pa. i have reviewed his loa and indeed it was oley pa. my question is stated in many sources that john lived his whole life on the milbach. how could this be if conrad and catharine moved to oley pa in 1775. any help? please contact me. allan e leffler
